section 6:

"We require that all CAs whose certificates are distributed with our
software products:
verify that all of the information that is included in SSL certificates
remains current and correct at time intervals of thirty-nine months or

My reading of that is that if it ever comes to pass that a certificate
signed by your CA has not had the information within it revalidated in
the last 39 months, and is still valid, then that's in violation of this
policy item.

This is obviously not a problem if you issue certificates whose lifetime
is 39 months or less and you get fresh information at the time of cert
issuance; but if you issue certificates which last longer, or you issue
certs based on old information, you need to make sure that the
information is revalidated on or before the date it reaches 39 months
old. If this is not done, I would expect the cert to be revoked.

There is no problem with revalidating the info while the cert is still
in use. And if the info remains the same, there is obviously no
requirement to change the cert or otherwise interrupt service.

Kathleen is away at the moment; but any CA who disputes this reading is
welcome to drop Kathleen and I a line.
